But on Wednesday, groups have begun to gather at the gas station where he was shot — including locals, veterans of the Ferguson protests, and police.

The NAACP has called for peaceful gatherings. But Berkeley is still on edge, especially after the string of protests in nearby Ferguson this summer following the shooting death of 18-year old Michael Brown at the hands of a white police officer.

Berkeley is 85% black, and has a population of 9,000 — about half the size of Ferguson.

After Martin was killed Tuesday, hundreds gathered at the gas station, some clashing with police and throwing explosives — likely fireworks — and rocks.

Local authorities allege Martin, who was the same age as Brown, pulled a gun on a 34-year old white police officer. The officer then fired three shots, one of which fatally wounded Martin.
